When it comes to construction, transportation, and machine manufacturing, non-standard hex bolts play an important role to keep everything in place. Non-standard hex bolt is a fastener with six sides of a hexagon shape with varying length, width, and dimensions depending on the application. A non-standard hex bolt is a fastener that does not meet standard industry specifications, but are custom made to fit specific purposes. These bolts are versatile, durable and available in different grades, materials, surface finishes and sizes for a diverse range of applications. The following is a comprehensive introduction of non-standard hex bolts that will help merchants understand the product.




Non-standard hex bolts can be made from different materials like steel, stainless steel, brass, and titanium. The materials used could depend on the specific application requirements, desired strength, resistance to corrosion, and aesthetic appeal. Steel and stainless steel are commonly used materials because of their durability, strength, and resistance to rust and corrosion. Titanium is also a popular material used for non-standard hex bolts that are used in aerospace and medical industries where lightweight durable materials are required.




Non-standard hex bolts are available in different grades, which determine the strength of the bolt. Grade refers to a metric that is used to identify the mechanical characteristics of the fastener, and some of the grades include grade 2, grade 5, grade 8, and grade 9. The grade of the hex bolt affects its mechanical properties, such as strength, corrosion resistance, and ductility. The higher the grade, the stronger and more durable the non-standard hex bolt will be.


Surface Finishes


Surface finish refers to the coating or treatment applied to non-standard hex bolts to protect them from corrosion and rust. Some common surface treatments and coatings include Electroplating, Black oxide, Zinc Plating, and Hot Dip Galvanizing. A surface finish enhances the appearance of the fastener, protects it from external factors like humidity, water, and oxygen, and can also serve functional purposes like improving the conductivity or lubricity of the fastener.




Non-standard hex bolts are available in different sizes and dimensions to fit specific applications. The diameter and length of the bolt will depend on the threading requirements and the size of the hole that it will be fastened into. As non-standard hex bolts are made to custom specifications, the size range can be vast, allowing for applications that require a unique fit.




There are many advantages to using non-standard hex bolts in manufacturing and construction applications. One of the primary benefits is their versatility, as they can be custom made to suit specific application requirements. They are also more durable and sturdy when compared to standard bolts, making them ideal for high-stress applications. Due to their custom nature, non-standard hex bolts can be used in a variety of places, especially in unique or challenging situations where standard bolts would not work.




Non-standard hex bolts can be used in a wide range of applications, including construction, transportation, machine manufacturing, and agricultural equipment. They can be used in any application where standard fasteners are not suitable or the required fittings are not available, making them perfect for bespoke manufacturing. Some of the standard applications include machinery, automobiles, medical equipment, and construction, where they're used to fasten or join different parts together.




An important point to consider when purchasing non-standard hex bolts is to make sure they suit your specific application requirements. As non-standard hex bolts are made for specific purposes, it's essential to work with a trusted manufacturer that can understand your needs and create custom bolts with the right specification. At our manufacturer, we have the expertise, equipment, and quality assurance processes in place to create non-standard hex bolts according to your exact specifications. We also provide multiple services like CAD design, material selection, and testing to ensure that our customers receive high-quality products that meet all relevant standards. With our expertise, customers can expect customized non-standard hex bolts for any challenging application.



We are a non-standard fastener manufacturer with nearly 20 years of experience. We can customize Non-standard Hex Bolts for you according to your needs. Our products are strong, durable, and corrosion-resistant. They have outstanding performance in three aspects: load capacity, applicable place, embedded depth. These three aspects are the core to test a good screw. And our products do good in those aspects. Welcome to consult and order them.


1. They can bear larger loads: they have six force-bearing surfaces, which are more resistant to screwing than flat-head screws and cross-shaped screws with only two surfaces.

2. They can be countersunk in use: that is, the whole nut is sunk into the workpiece, which can keep the surface of the workpiece smooth and beautiful.

3. Easy installation: suitable for more occasions, especially narrow occasions.
